To a whom it may concern:

Be it known that we, HERMAN DUSTMANN, residing at Lawrence, in theparish of Plaquemiues and State of Louisiana, and WILFORD H. HOLSCLAW,residing at Louisville, in the county of Jefferson and State ofKentucky, citizens of the United States, have invented certain new anduseful Improvements in Cultivators; and we do hereby declare the fol- 1olowing to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to improvements in cultivators, and has for itsobject the production of a cultivator in which the frame carrying thecultivator blades or bursterplow may be adjusted easily by the operatorof the cultivator from his position upon the seat of the machine and onealsoin which the standards supporting the blades or plows of the devicemay be readily adjusted to different depths or different verticalpositions with relation to the remainder of the machine. It consists ina cultivator having suitable supporting-wheels, an axle, an arch mountedthereon and braced with respect to the pole, a frame pivoted to the saidaxle and movable with relation to the pole'and arch, and means 0 foradjusting the said frame, so as to raise or depress the rear end withrespect to the ground being operated upon.

It also consists'in certain other novel construc-tions, combinations,and arrangements 3 5 of parts, as will be hereinafter more fullydescribed and claimed.

In the accompanying drawings, forming a part of the present invention,Figure 1 is a perspective view of a cultivator, illustrating thefeatures of the invention. Fig. 2 is a top plan view of the rear end ofthe cultivatorframe. Fig. 3 is a side elevation of the same. Fig. 4 is aperspective view illustrating the manner of constructing the arch, whichrests upon the axle of the machine. Fig. 5 is a rear elevation of thesame. Fig. (i is a perspective view of the cultivator provided with adifferent means of securing the standards to the cultivator-frame. Fig.7 is a side elesaid bearings.

vation of a portion of the same, the wheels being removed to betterreveal the parts.

In embodying the invention in practical form theaxle 1 is employed,which is provided with a central offset or crank-shaft portion, as 2,upon which the cultivator-frame 3 is pivotally supported. Above thecrank portion 2 of the axle 1 is arranged an arch 4, adapted to supportthe tongue 5 of the machine. The arch 4 is made in a very simple mannerand in a way to be easily applied upon the axle, comprising twoseparable parts 6 6, each of which is formed of a vertical portionhaving an enlarged lower end 7, provided with an aperture which may beslipped upon the axle 1. The upper ends of each of the pieces 6 6 arebent inwardly and made to lap upon each other, as seen at 8 in Fig. 4.These lapping portions are provided with a series of bolt-holes 9 9,through which rivets or bolts may be passed for holding the partstogether. By providing these pieces with a series of bolt-holes thewidth of the arch may be adjusted, if desired. These bolt-holes alsoprovide means for securing the rear end of the pole 5 in position, abolt or rivet 1O securing the said pole to the said arch. Theseatstandard 11 is also clamped to the said arch, as at 12, so as tohold the seat in proper position with relation to the machine.

The frame 3 of the cultivator is'made up of a central beam 13, which isformed of two bars applied parallel to each other and spaced by suitablewashers, so as to be adapted to receive between them the standards ofcultivators or burster-plows, as may be desired. This beam 13 is securedto a casting 14, which is provided with bearings 15, adapted to engagethe crank 2 of the axle 1. The said crank is held in position in thesaid bearings by means of bearing-plates 16 16, which are bolted to thecasting 14, and thereby hold the said crank pivotally in engagement withthe It will thus be seen that by rotating the axle 1 the crank 2 willoperate tolift or depress the cultivator-frame 3. The forward end of thebeam 13 is extended some little distance beneath the rear end of thepole 5 and is connected with the said pole by means of a yoke formed ofside pieces 17 17, which are pivotally secured at their lower ends uponeach side of the said beam 13. Each of the pieces 17 17 is provided witha series of apertures, as 18, through which bolts may be passed. Onebolt, as 19, is preferably passed through a pair of openings, so as torest upon the top of the pole 5, while a second bolt, as 20, is passedthrough a pair of openings, so as to engage the under side of the saidpole. The yoke 17 affords a means for altering the relative positions ofthe beam 13 and the pole 5. Side wearing-plates 21 are preferablysecured to the pole 5 to relieve the pole of undue wear at this point. Abolt 22 is also passed through the pole 5 in advance of the pieces 1717, so that the head of the said bolt on one side and the nut on theother side of the pole 5 will limit the forwardmovement of the yoke. Therequired movement of the yoke is limited by the upper ends of thediagonal brace-bars 23, which are connected with the pole 5 by asuitable rivet or bolt at their upper ends and at their lower ends aresecured, as at 24 24, to the arch 4. These brace-bars 23 therefore notonly serve to limit the movement of the yoke, but also serve to bracethe lower ends of the arch 4 with respect to the pole 5. Between theforward ends of the plates forming the beam 13 is secured an eyepiece,as 25, forming a clevis, into which the hook of a doubletree 26 may besecured. By this means the team for drawing the cultivator will beattached directly to the beam 13.

The construction of the frame forms an important feature of theinvention. To the rear ends of the beam 13, which forms the central beamof the frame, are secured transversely-arranged bolts, as 27 27, whichpass through the said beam and extend a suitable distance upon each sidethereof. Attheirouter ends they engage and support side beams 28 28,which beams are spaced from the central beam by means of sections ofgas-pipe or other tubes, as 29 29. This forms a simple and yetinexpensive means for properly spacing the side beams with respect tothe central beam. The side beams 28 are preferably formed of two barsspaced apart by means of washers, so that the standards of thecultivator-blades may be bolted between the said blades, and therebyfirmly secured to the beams.

As seen in Fig. 1 of the drawings, the cultivating means preferablycomprises cultivating-blades, as 30, and a burster-plow, as 31. Theburster-plow may be of any suitable construction and is provided with astandard 32, which is bolted at its upper end between the bars formingthe beam 13. This standard is also provided with a bracebar, as 33,which is secured between the bars of the beam 13 in the rear of thestandard, so as to thoroughly brace the plow in position. The blades 30are preferably of usual construction and are each secured to a casting34, which is attached to a pivotal shoe or piece 35,

which is bifurcated at its upper end. The lower end of theblade-standard 36 preferably extends into the bifurcated portion of theshoe and is pivotally secured thereto by a bolt 37. The upper bifurcatedends of the said shoe are preferably provided with seg- .mentalelongated slots 38, which are adapted to be engaged by a bolt 39,passing through the standard 36. By loosening said bolt the elongatedblade 30 may be adjusted with respect to the standard 36. The standard36 preferably extends upwardly between the bars forming the side beams28 and is provided with one or more bolt-holes, so that it may be boltedin the said beam at any desired height. A brace-bar 40, having abifurcated lower end, is pivotally secured to the standard 36 and at itsupper end extends between the bars of the beams 28 28. The upper end ofthis brace-bar 40 is also provided with a series of apertures, so thatthe angle of the said standard 36 may be regulated with respect to thebeam 28. The brace-bar 40 may be arranged in the rear of the standard36, or when the said standard is placed near the rear end of thecultivator-frame the said brace-bar may be arranged in front of thestandard, all within the scope of the present invention. Ifdesired, inplace of the bursterplow 31 a blade similar to 30, with its appropriatestandard and brace-bar, may be employed instead, it being securedbetween the bars of the beam 13 in the same manner that it would besecured to the bars of the beam 28.

In order to raise and lower the cultivator, so that its blades and plowmay go to greater or less depth in the ground or may be lifted entirelyout of engagement with the same, a suitable means is provided forrocking the axle 1, and thereby raising and lowering the crank 2. Toaccomplish this purpose, a bellcrank lever, as 41, is pivotally securedupon the said axle l, and one of its ends is pivotally attached, as at42, by means of a suitable casting to the crank 2. Its other end ispivotally engaged by means of a bifurcated bar, as 43, which is alsopivotally secured at 44 to the lower end of an operating handle or lever45. The lever 45 is pivoted to the arch 4 at 46 and is provided with aspringoperated latch 47, which engages a segmental rack 48, also securedto the arch 4. The handle of the latch'is arranged in suitable proximityto the handle of the lever, so that the operator of said lever can havethe latch within complete control. In order to assist the operator inraising the crank 2, a spring 49 is secured near the upper end of thelever 45 and is attached to the rear end of the bar 43, as at 50, therear end of the said bar projecting beyond the end of the lever 45. Theweight of the cultivator is thus somewhat equalized, and this renders iteasy for the operator to raise or lower the cultivator-frame. The lever45 extends upwardly to a convenient position with respect A suitablefoot-rest may be atto the seat.

tached to the tongue 5 by using a bar and bolting the same by means of aclip 51 to the said pole 5. This bar preferably extends a suitabledistance upon each side of the pole 5 and is made concaved to morereadily engage the feet of the operator.

As seen in Figs. 6 and 7 of the drawings,

the arrangement of some parts of the device may be readily alteredwithout departing from the spirit of the invention. As seen in thesefigures, the beam 13 may be secured to a casting 52, which is suspendedbelow the crank 2 of the axle 1. In this instance the said casting isformed with a depending piece 53, which extends to one side of the beam13 and is bolted thereto. The said bolt also passes throughforwardly-extended bracepieces 54, which are made by extending from eachside one of the bars forming the side beams 55 of the cultivator. Thecap-pieces 56 56 for holding the crank 2 in the bearings of the casting52 are also connected by a crosspiece 57, to which an equalizing-spring58 is attached, the said spring extending forward a suitable distanceand being attached to the pole of the cultivator. Such a spring assistsin lifting the weight of the cultivator-frame and aids the spring 49,heretofore described.

The mechanism-for operating the axle 1 and the crank 2 isthe same asheretofore described, and its action is also the same. As seen in Figs.6 and 7, the side beams 55 55 of the cultivator-frame are spaced apartby spacing-blocks 59, so as to make the space between the bars of thesaid beams wider than those shown in Figs. 1 and 20f the drawings. Thisarrangement of the bars of the said beams facilitates the use of blocks,as 60, for attaching the standards of the blades to thecultivator-frame. These blocks 60 are preferably castings and areprovided with apertures 61, adapted to engage a slide upon one bar ofeach beam 55, while the ends of the said block are bifurcated, as at(52, and embrace the other bar of the said beam. The blocks are thusrigidly held in position upon the said beams. The blocks are made so asto extend a suitable distance to either side of the beam and areprovided with vertical openings, as at 63, into which the upper'ends ofthe blade-standards may be inserted. By having two or more of suchopenings the distances of the said standard from the said beams of thecultivator can be regulated as desired. A securing-bolt is passedthrough the said block for attaching the standard rigidly in the saidopening. By the use of these attaching-blocks the standards may bearranged upon either side of the side beams and two or more standardsmay be carried by each of the said beams, as seen in Fig. 6. Theemployment of these blocks makes it possible to use a greater number ofblades than with the construction heretofore described.

It will be seen from the above description that our improved cultivatormay be made with great strength, and yet that the parts are allexceedingly simple and maybe cheaply manufactured. It will also be seenthat the range of adjustment is large and that the position of theblades and burster-plow can be varied as may be found most suited to thework in hand.
